FIELD: mining industry. SUBSTANCE: this relates to devices for clearing cutting faces of bore-holes from ferromagnetic articles. For higher load lifting capacity, easier manufacture and repairability, one of magnetic circuits in magnetic unit of catcher is made in the form of strip with one or several longitudinal and circular slots in which permanent magnets are seated. Other magnetic circuit is made in the form of strips or circular disks according to number of slots in first magnetic circuit. EFFECT: high efficiency. 2 dwg
